A Vietnamese man took part in the Boston Marathon in the US, in which two bombs ripped through the crowd at the finish line on Monday, killing three people and injuring more than 170 others. But there is no information about the man’s condition. The athlete is Ho Van Dung, as shown in the list of the competitors that Tuoi Tre found on the website of the event. Dung is 38 years old and was given code number 25957 by the marathon’s organizer. No other information is known about him. However, Nguyen Manh Hung, deputy general secretary of the Vietnam Athletic Federation, told Nguoi Dua Tin news website that the federation has not sent any Vietnamese athletes to the Boston Marathon. Athletes at the marathon have either been invited to attend the event or personally registered for participation, Hung said. Therefore, “Dung might have registered to engage in the event as an individual and such a case has nothing to do with the Federation,” he said.          Phan Huy Dung, President of the Vietnamese Student and Youth Association in the Greater Boston, yesterday said, “We are trying to obtain information about whether any Vietnamese students have been injured or otherwise affected by the bombings.” There are about 1,000 Vietnamese students studying in the Greater Boston area, said Huynh The Du, who is post-doctoral fellow at Harvard and former president of the association. The area is home to tens of thousands of Vietnamese people, one of the populous communities of Vietnamese in East Coast of the US. After the deadly incident, the Boston Athletic Association, which hosted the Boston Marathon, issued a statement in which it extended its deepest sympathies to all those who were affected by the bombings. US President Barack Obama on Tuesday called the bombings an "act of terror", and police said parts of central Boston could be closed for days. It was the worst bombing on US soil since security was tightened after the attacks of September 11, 2001, and President Barack Obama promised to hunt down whoever was responsible for the attack on a day when tens of thousands of spectators packed the streets to watch the world-famous race, Reuters reported.
